Re: makecontext friends ?

Hi, Sure, it can. See my GNU Portable Threads under http://www.gnu.org/software/pth/. We have a port under devel/pth, too. It bases its user-land threads on ucontext(3) if available or on setjmp(3)'s jmp_buf, etc. All without any assembler things. For details read my USENIX paper under
